ALBERT RIGAUD, OF ST. JUNIEN, FRANCE.

SPECIFICATION forming part of Letters Patent No. 691,075, dated January 14, 1902. Application led October 25,1900. Serial No. 34.393. (No model.) l

To ttZZ whom it may concorre:

Be it known that I, ALBERT RIGAUD, a citizen of the Republic of France, and a resident of St. Junien, (Haute-Vienne,) France, have invented Improvements in Machines for Mechanically Dyeing I-I-ides, Leather', and other Like Articles, of which the following is a specification. y

This invention relates to a machine for dyeing leather, hides, and like materials, and has for its objects to preventthe waste of the niordant,dyestnff,orxing materials used for this purpose, to effect a more regular application of the dyeing materials to th'e hides, to insure good dyeing .results without depending-upon skilled labor, and also to provide means for successively applying mordant, dyestuif, and lixing material to the continuouslymoving hides. l y

In the accompanying drawings, Figure lis an end view, partly in section, of the apparatus. Fig. 2 is a View showing a modified spraying device. Fig. 3 is a plan view of half the apparatus of Fig. l, and Fig. 4 is a similar View of the remaining half.

a is the main frame of the machine.

a' represents supporting pieces or arms for the rails b, on which the hide-supporting carriage c is adapted to run. The top c of the carriage is preferably of polished glass, enameled sheet metal, ebonite, or the like.

To complete the dyeing in one travel of the platform without an unduly long frame and to have the platforms near the starting-point at the completion of the operation, I make my frame half the necessary length, but with two sets of rails, and cause the platform to travel first up one side and then onto a transfertable p, having rails h coinciding With the rails b of the frame and itself adapted to be moved at right angles to the frame by means of suitable wheels secured thereto and adapted to travel on the rails o. This table p in its second position will have its rails in line With the rails of a return side of the frame, whereby it will become possible to return the carriage to the starting-point upon the oompletion of the operation hereinafter described. The starting end can with advantage have a similar transfer-table and rails. To the frame and beneath the outer edges of the platform I secure gutters d, having drain-pipes d,lead ing to any suitable receptacle y.

The platforms are advanced along the` rails l? by the following means: A driving-pulley Pis mounted on a shaft 7c, extending from one side of the apparatus to the other. Counter-shafts 7a2 lo', suitably geared to the driving-shaft, but revolving oppositely to each other, have mounted thereon chain-.wheels zu, by which endless chains Z Z are adapted to be operated in the directions of the arrows in Figs. 3 and l. At, suitable intervals along these chains there are secured projections x, adapted to project a distance above the chain and to come into contact with such platforms c as may be at that time on the rails, and thus cause them to be traversed until they have been passed out of the path of these projections as will be readily understood.

To the frame o., above the path of travel of the platforms c, I secure transverse beams e. These beams act as guides for holders g,

adapted to carry the tanks h and to be reciprocated by the following mechanisms: A shaft n, at right angles to the shaft lo and geared thereto by bevel-gears, is, by a crank n' and connecting-rod n2, adapted to operate a bell-crank lever m', mounted in a suitable bearing at m2, and to reciprocate -the same upon the revolution of the shaft n. other end of the bell-crank lever m is pivoted a rod m, the other end of which is pivotally connected to the holder g. In mytwotrack apparatus a second holder gw over the returmtrackis fastened to the first holder by a horizontal rod g. By this means a continuous to-and-fro movement is imparted to the holders. I may have any number of such holders. 'l In the apparatus of Figs. 3 and 4 I have shown four sets of two operated by individual bell-cranks and connecting-rods. The holders g are adapted to accommodate a number of tanks 71, each of which may be simply a rectangular box having an inlet and piping r and an outlet provided with asprinkler S. Any number of these tanks may be provided to a holder, and they may be adjustable in such holder in the direction of its length sliding between the side pieces s".

In Fig. 2 I have shown a modified form of sprinkling device. It consists of a feed-pipe 'ro nre ICO . are secured. To these distributing-tanks I lead a pipe r' from the bottom of separate containers s with size, dye,'or'the like contained therein. A tank t' is provided with air 'u nder pressure, which is conveyed` to the top of the containers, and thereby forces the liquid out of them to the distributing-tanks i.

'When treating the hides with different liqnids, as in carrying out different steps of a process,`each gutter, with its corresponding tanks, piping, and container, may be separate from the others, thereby insuring a separation of the various elements. One air-.tank only, however, is required.

In operation the hides are stretched on the platform, the chains are set in motion, and the platform is pushed into position so as to be engaged bythe projections x of the chain,

by which it is set in motion in the direction vof the arrow on the upper half of Fig. 4. Liquid in the first containers is forced to the distributingtan k and the first two tanks h h, while :liquid from thev second container s is forced to the third and fourth receptacles in the reciprocating holder g, thus spraying the hides on the platform as they pass beneath.

This operation is repeated at the other end of the machine, Fig. 3, with duplicate apparatus, forcing another liquid'for a second step of a leather-treating process, for instance. The platform is then advanced to the transfer-table and returns through a similar gaunt- .let of sprayers adapted to spray a third or even a fourth liquid of a process for treating leather. The excess of each different liquor is taken from the gutters to separate receptacles 'y and returned for reuse.

I claim as my inventionl. A machine for dyeing hides and the like, comprising a frame, a movable platform thereon, spraying devices above the platform but not in contact therewith and means for causing the spray to travel from side to side of the movable platform, substantially as described.

2. A machine for dyeing hides or the like, comprising a frame,a movable platform therefor, to which the hides are secured, spraying devices above but not in contact with the hides and means for reciprocating said spraying devices from side to side of the platform, substantially as described.

3. A machine for dyeing hides, or the like, comprising a frame, a movable platform therefor, a holder g above the platform, means t-o reciprocate it from side to side above the platform, and spraying devices in the holder adjustable therein, substantially as described.

4. A machine for dyeing hides or the like, comprising a frame, and movable platforms therefor, in combination with sets of spraying devices over the platforms, a separate container for each set of spraying devices, separate gutters and tanks therefor under each set whereby on placing different liquids in lthe separate containers and traversing the platforms lthe successive steps of a process may be carried out as described.

5. A machine for dyeing hides, or the like, comprising a frame, a longitudinally-movable platform thereon, said platform being higher above its center line than at the sides, and gutters secured to the frame beneath the sides in combination with spraying means above the platform, substantially asgdescribed.

In testimony whereof I have signed my name to this specification in the presence of two subscribing Witnesses.
